    A guy I work with was telling me the other day that guys are taking turbos off VW's and adapting them to Toyotas. Anyone know if there is any truth to this?

    Yea probably is true. But you can't just run out and get any old turbo it has to be the right size.

    Ya that's what I thought. This guy told me that the VW turbos don't make much more than 8 or 9 pounds of boost so it's not a big deal. I don't know very much about turbos. LOL.

    They are pathetically small.

    If your going to adapt a turbo to a yota, might as well be a decently sized one.

    Yeah, kinda depends on what you want to do though. The advantage to a smaller turbine is that it would spool quicker, making it more fun to drive on the street. Of course, then you can go too small, restricting off boost power.

    get an electronic actuated controlled variable geometry turbo! THEE best! Also known as a VGT Turbo, more commonly found on BIG BLOCK I-6 Diesel's.... also ford powerjokes :D
    basically it controls a nozzle which can vary exh. backpressure and at the same time, pretty much boosts the engine right off of the line... or wait a few more years and get what is currently undergoing continuous research, development and crazy mad testing... manufacturers are coming out with ELECTRONIC MOTOR driven turbos.... which will be a lot more efficient than a supercharger or turbo setup!


    Damn school is paying off :D

    Just read about the turbo's before you get one. You have to make sure you're getting the right size but also the A.R plays a big factor in how it spools. Not to mention if you go too small you could trash it over boosting and too big you may never spool it or only make boost at like red line lol

    or more like if you get to big of a turbo sure it will only make 5 lbs of boost but it will output so much volume, won't even be funny...

    But 5psi is 5psi regardless.

    So basically what all of you are saying it's a waste of time? I may as well look for a TRD turbo?

    Well keep it simple. A CT20 on a 22RTE is small and limits output pretty bad.

    The smallish CT26 on 7MGTEs is a nice upgrade for the 22R.

    Now depending on what you want to do, a 250 dollar ebay T3/T4 hybrid with a decent trim/AR will give all the potential your motor could handle.

    Sure a TDI or a 1.8VW turbo would give a NA 22R power, but a real screamer? Doubt it.

    At low psi like 5 or so...yes 5 psi is 5 psi.

    But once you jump into the 15 or 20 range...the turbo it comes out of makes a drastic difference and can have a HUGE play in horsepower and safety of engine.

    Running small turbos off of VWs as twins on a bigger toyota engine wouldnt be a bad idea. I know a guy who is twinning his 3.4 v6 with small turbos that came off of saabs...going to be beast.

    My supra gets the turbo off of a cummins turbo diesel truck...its massive lol.

    turbos are relatively universal if you have much fabrication ability.

    I'd shoot for a t3/t4 set up. I'm running a gt35r on my 2rz and thats really big for that motor. Just look up what other people have been using. I know there are a few guys on here that have had boosted 22r's.

    Look at the enginiered kitss out there for toyotas first. then do the reasearch, there are tons of books about boosting. Also the tripple K turbos for VW TDI's have an ar of 91 and will make 8 lbs of boost at low rpm. VW deisels are high rev bbut still max out around 4600 rpms. If you go this rout just make sure you have good oil flow through the turbo and use a good intercooler. There is very little gain at low boost if the air is hot. I have used these on several engines and they work well. but if you are in dought find a turbo from a like sized engine. ford 2.3 turbos are a good source to. I curently hane a nissan turbo on mine and run 10 lbs. It's small but higher boost with proper fuel makes up for size. good luck in your quest for horse power.

    The turbos are from most of the 1.8T's. That's 1.8L of airflow, and it was made for economic reasons, hence the superquick low rev spool.

    I'd get some t4/t3 turbo for our trucks to make the best of your time.

    5psi isn't just 5psi....

    a small gasoline turbo outputs so much volume at 5psi...
    a HUGE DIESEL SNAIL outputs WAY MORE AIR at 5psi...

    Do more researching, you'll find out I am right ;)

    So it's like a tire right? A smart car's tire at 30 psi has less volume than a bulldozers tire at 30 psi correct? And if you add more psi they both go BOOOOM!!! :ROFL:

    not really but in a sense yes, you got it tony!

    a tractor trailer tire at 30 psi holds more volume of air rather than a prius tire at 30 psi...


    point i was makin at my op, you cant put a big ass turbo with 5 psi on a smaller engine, too much voulme, your piston will essentially go BOOOM!!!
